The property is a
semi-detached bungalow. It is situated on the inside of a bend of Cottingham Grove, such that the road runs
parallel to the front elevation of the house, but at an angle to the side elevation (please refer to the OS
map). The application was for a proposed single storey side extension and a proposed single storey rear
extension. The roofs of both of these extensions would join onto the roof of the main house (which itself is
single storey), with eaves at the same level and a ridge-line at a lower level.

The key issue was whether the
proposed side extension would be contrary to Class A, part A.1(d), which states that “Development is not
permitted by Class A if … the enlarged part of the dwellinghouse would extend beyond a wall which— (i) fronts a
highway, and (ii) forms either the principal elevation or a side elevation of the original
Dwellinghouse”.

The Inspector stated the
following:

“The property does not sit
on a true corner plot where the side elevation would, in all likelihood, front the highway. Neither does it form
part of a row of semidetached properties sitting parallel with a highway where the side elevation would face the
neighbouring property. The side elevation sits at an angle to the highway and there is no dispute that the front
elevation fronts the highway; being almost parallel to it. In addition the side extension would not extend
beyond the front elevation.

When stood in front of the
side elevation, looking out, the highway can be seen as can the side elevation of the garage in the adjoining
property. The view is at an acute angle to the highway and although there is a curve in the road, the highway
does not run anywhere near parallel to the side elevation. Given the oblique angle at which it sits next to the
highway, it could not, in my judgement, be considered to be fronting onto it”.

Although not specifically
addressed by the Inspector, the fact that this appeal was allowed implies that Class A does permit an
extension with a roof that would join onto the roof of the main house.

Main
Conclusions:

·Class A does permit an
extension with a roof that would join onto the roof of the main house.[Note: This would appear to contradict
at least one other appeal decision – for further information see the entry in the “Reference Section” on
“Interaction between Class A, Class B, and Class C”].[Relevant to: “Interaction between Class A, Class B, and
Class C”, Class A, A.1(i), Class B, B.1(c)].
